Neutrino Exploit Kit via EITEST sends updated CryptXXX Ransomware
- Today I captured traffic from the latest version of CryptXXX ransomware. The ransomware was delivered via the EITEST campaign.
- Some changes noted to this version of CryptXXX were, it renames the file and extensions to random alpha numeric numbers and is using a new command and control (C2) host.
- For a more detailed analysis of the EITEST and CryptXXX traffic, see my post Neutrino Exploit Kit via EITEST 126.96.36.199 sends CryptXXX Ransomware.
I have added a zipped pcap file for your analysis. The password is the usual used by malware researchers. If you do not know it please email me.
